The second part of my Thanksgiving Day work. Actually, third. Yesterday we spent all day making potato and cheese pierogies (pirohi) from scratch. No, I'm not, but yes, my sibling are both the grandchildren of Ukrainians. I grew up with them, we have pierogies at holiday meals or I guilt trip my mother for 40 days and 40 nights. The end.
Anyway, this is great, and works on plain rolls, or The Family Cinnamon Rolls.
1 stick salted sweet cream butter, room temp
1/2 cup + 2 Tbsp. confectioners sugar
3 tsp. cinnamon
Depending on the brand of butter, cinnamon and sugar should be adjusted. I recommend spooning it in and taste testing here and there.
Beat the butter smooth. Then add sugar, a bit at a time, because using a beater you'll end up with a sugary cloud of doom if you don't. Add cinnamon to taste. Whip it good. Spoon into container, and you can refrigerate.
